Does this recipe actually work? Recipie for 500-600whp Junkyard Turbo LS build
quick and dirty it goes like this
acquire junkyard LS engine, leave it totally stock other than installing Pac1218 valvesprings and boost it, or install a turbo cam under .600 lift (limit of the pac1218s)
install 80lb siemens deka injectors in stock intake, add 044 external or walbro400 internal fuel pump to vehicle (proven to support over 600whp so far by themselves)
3/8ths fuel line is fine, install any chinese 70-80mm turbo ($220-550, and 50-60mm wastegate $60-120)
use megasquirt or stock pcm and tune it or have someone tune it on pumpgas and methanol... wham 500-600whp

I’m a pretty good fabricator,I think they look better and would be easier for me to run the exhaust also what brand turbos should I look at that will be very reliable

Also this is going in a 64 Chevelle
on my bucket list is for me and my wife to drive it coast to coast so I’m totally modernizing it with ac,big brakes,power steering and ect
with this build I need the whole car to be reliable so are there any other motor upgrades to make it more bulletproof also can I one tune for horsepower and another tune for fuel efficiency

I understand if you want the look. Twin turbo's do look cool.
BorgWarner, Garrett, and Precision all make very nice turbos.
I like BorgWarner the best.
A lot of people are getting away with the cheap Chinese turbo's these days.
You can run two different tunes, but it sounds like you need to do a lot of research.
These are all very basic questions that can be found by searching this forum.
Good luck with the build. This forum is jam packed with info.

I'm working on a low power twin set up right now and all I keep thinking is WHY
Twice the amount of work, twice the amount of stuff to go wrong and break....for the same amount of power.
At least it's nearly twice the amount of billable hours for fab work

I dunno, I've done $800 twin setups before that made a few things very simple. No crossover, no merges, two smaller downpipes easier to fit than one larger one, two small turbos much easier to fit than a big single, etc. They do have their benefits.
Stock truck manifolds, a pair of 14 gauge 2.5" U-bends, and 2.5" to T3 transition flanges. Entire hotside done in a couple of hours.

Why not just split a single turbo exhaust into two smaller diameter pipes? At this power level, I think the only reason for twins is if you can't fit a single turbo in the engine bay.

Here is an exact recipe I did 3 times all made between 6 and 620 hp. Stock ls1 or bored out 5.3 to 3.903 bore forged pistons are 600bux so buy them instead of methanol kit. Tick stage 1 or 2 turbo cam can be got used on here for 200 to 300. On3 76mm or 88mm turbo. Aeromotive 340lph in tank pump and boost referenced regulator 130 for pump 120 for regulator I made over 600 3 times with a th400 th350 and th400 again. It's a cheap build but it's proven reliable more than a lot of people's builds I see. U can use stock rods and pistons if u want but I'd run meth even at 6psi it's just a nice fail safe in my eyes also 600hp can be done with deka 60s if money is tight

Or run decapped injectors, find a stock ls1 or l33 camshaft for cheap or free. I made close to 600rwhp with an L33 vavle springs only at just under 13lbs. I wouldn't spend any money on the motor if don't have a good grasp on tuning. Good parts will burn up just as fast if the tune is off.
